How is the working principle of solar cells convert solar energy into electrical energy. Solar cells that we see is a set of modules photovoltaic cells (photo = light, voltaic = electricity) is a well-crafted, neat and packaged in the form of a frame. Tues photvoltaic will convert solar energy directly into electricity.
Photovoltaic cells are made of special semiconductor materials are now widely used and referred to as silicon. When the light on silicon cells, the light will be absorbed by these cells, this means that the absorbed light energy has been transferred to a silicon semiconductor material. The energy stored in this semiconductor will result in loose and flowing electrons in semiconductors. All of these photovoltaic cells have electric fields that force electrons that escape because of light absorption to flow in a certain direction. This flow of electrons is electric current, by putting the terminal contacts on the top and bottom of these photovoltaic cells will be seen and measured the current flowing so it can be used to supply external devices. This above is a basic change in the solar energy into electricity by a semiconductor silicon. This is the working principle of solar cells.
